Laravel Collections - la function collapse()

Pour cette 4e partie nous allons évolué encore un peu plus et cette fois parlé de la fonction collapse

#Description

Si tu as bien suivi ce que l'on a dit sur la méthode chunk() dans la partie 3, collapse() sera facile !

C'est l'exact inverse, en gros, collapse() recolle les morceaux !

#Exemples d'utilisation

**Code source #1 : on 'chunk' et on 'collapse' **

 1$languages = collect([
 2  "php",
 3  "python",
 4  "javascript",
 5  "go",
 6  "c#",
 7  "java",
 8  "cobol",
 9  "basic"
10]);
11$chunked_languages = $languages->chunk(3);
12echo "<h2>CHUNKED</h2>" . PHP_EOL;
13print_r($chunked_languages);
14 
15$collapse_languages = $chunked_languages->collapse();
16echo "<h2>COLLAPSED</h2>" . PHP_EOL;
17print_r($collapse_languages);
 1$languages = collect([
 2  "php",
 3  "python",
 4  "javascript",
 5  "go",
 6  "c#",
 7  "java",
 8  "cobol",
 9  "basic"
10]);
11$chunked_languages = $languages->chunk(3);
12echo "<h2>CHUNKED</h2>" . PHP_EOL;
13print_r($chunked_languages);
14 
15$collapse_languages = $chunked_languages->collapse();
16echo "<h2>COLLAPSED</h2>" . PHP_EOL;
17print_r($collapse_languages);
